Post-traumatic trigeminal neuropathy: correlation between objective and subjective assessments and a prediction model for neurosensory recovery

Table 1 Prediction model for neurosensory recovery in PTN after 6 months

Variable	Coefficient	Confidence interval
Intercept	3.4109	[−1.4975; 8.3192]
Pain-VAS	0.048	[0.0079; 0.088]
% affected dermatome	−0.0316	[−0.071; 0.0078]
Sensory code Gain	−1.1032	[−2.3562; 0.1499]
2-point discrimination (affected side)	−0.1708	[−0.4153; 0.0737]

In the model, values for the pain visual analogue scale (Pain-VAS, 0–100), percentage of affected dermatome (0%–100%), gain-of-function sensory code (0–3), and two-point discrimination of the affected side (in mm) are multiplied by their corresponding coefficient. The resulting values are summed, and the intercept value is added to the total. For results ≥0, PTN is predicted to recover at 6 months. For values < 0, the PTN is predicated to not have recovered at 6 months
